FRDM-MCXN947: Target Mismatch detected

elby — Tue, 13 May 2025 11:14:55 GMT

Hi, I am new to NXP board and MCXpresso IDE. I am using FRDM-MCXN947 board where I am trying to execute a simple Hello World application. I am not sure if I am on the right path. I tried with Zephyr example it didn't work or perhaps nothing came up in the Serial Monitor when I tried to print message there (HELLO WORLD) .

Now, I am trying with MCXpresso IDE where I have picked the Hello world example from "Import SDK examples"- build. When I clicked "Debug" I was able to see the board and probe however I had this warning.

I carried on with "Yes" and this started to Debug.

I had the following issue:

Can some explain me what went wrong? Thanks in Advance.

Hi @elby

We can temporally ignore the warning.

To re-gain debug access, boot the MCu into ISP mode and then trigger a mass erase. Easiest way for doing this is by using the debugger, over SWD.

If you are having troubles, we can try to do a mass erase over LPUART/USB using the MCUXpresso Secure Provisioning Tool. You can also share a picture of your board jumper setup to double check settings and connections.
